Your Chrome
Works with the agents you already run
Connect Codex, Claude Code, Cursor, OpenClaw, Hermes, or another MCP host to FSB. Install the Chrome extension, connect the MCP bridge, and run doctor to verify access to your real browser session.
Meta
Muse
Meta's personal agent, and Muse Code in the terminal. Point either at FSB and the browsing happens on your machine, where your accounts already live.

Dots
Always-on agents that keep working after you close the tab. FSB joins a dot's toolset like any other MCP server, with every browser action verified.

Why FSB MCP is powerful
Browser automation usually means a headless instance you cannot see. FSB drives the user's actual Chrome session, and the MCP surface is built around four hard requirements: precision, observability, safety, and concurrency.
68 tools
One surface, no glue code
Read, click, type, navigate, vault, observe. All typed. All agent-scoped.
N agents
Identity and tab ownership
Server-minted agent_id per session. Tabs owned per agent; cross-agent calls fail loud with TAB_NOT_OWNED. Cap 1-64, default 8. No focus stealing.
0 leaks
Vault boundary, by design
Passwords and cards resolve inside the extension's encrypted store via fill_credential and use_payment_method. Never in chat. Never in args.
Live
Real Chrome, real session
Your cookies. Your extensions. Your saved state. change_report streams mutations on every action, no extra read_page round-trip.
Meet the FSB Skill
The canonical OpenClaw and Hermes onboarding path. Loads cleanly into a fresh runtime, runs the full diagnostic flow, and installs the bridge for any other MCP host on your machine.
Doctor first protocol
Runs npx -y fsb-mcp-server@latest doctor, parses the failing layer (package, bridge, extension, active-tab, content-script, config), and prints the next step. Exit code surfaces failure to the host.
Stdio config printer
Emits the canonical OpenClaw stdio block or the Hermes config.yaml entry to paste into your MCP config. Parity locked with mcp/src/install.ts so it never drifts from the installer.
Consent gated host install
Detects other MCP hosts (Claude Desktop, Cursor, Codex, etc.) and asks y/n per host before installing. Never --all without consent. Never auto writes the OpenClaw config.
One line to connect
Pick your host and the installer writes the smallest config entry it needs. Restart the client, open a normal webpage, and ask it to read the page. Run install --list to see all 21 targets.
Where FSB earns its keep
The recurring browser work. The boring, repetitive stuff that vision-based agents struggle with on logged-in sites. FSB runs in the user's real Chrome, so cookies, sessions, MFA state, and saved logins are already there.
Open Gmail, label everything from billing as finance, draft replies to support threads using yesterday's tone, and flag anything urgent.
In Zendesk, draft answers to open tickets about pricing, order status, and shipping using the help center as ground truth.
Pull yesterday's revenue, signups, and refund count from the analytics dashboard and post a one paragraph summary.
Score new LinkedIn connection requests against the ICP, draft outreach for the top three, and skip the rest.
Categorize today's invoices in the POS as supplies vs. retail, extract shipping line items, and flag any vendor over last month's average.
Watch the price on this listing and tell me when it drops under $400. Keep the tab open, do not reload unless it stops updating.
These run as manual-mode tool calls. Autopilot (run_task) only fires when the user explicitly delegates the whole task: "use FSB autopilot", "delegate this", or names run_task directly.
